Describe the challenges facing megacities and evaluate the responses to these challenges
Mega Cities are cities that have a population of more than 8 million and are characterised by the challenges they face, including issues involving the informal economy, unemployment, poor sanitation and shelter. These issues are largely prominent in these cities due to rapid urban growth and a lack of resources. In many cases action has been taken by national governments and non-governmental organisations (NGO's) to combat and reduce the impact of these issues, however In order for these strategies to be effective they need to fit 3 primary criteria, the solution must be community based, cost effective and sustainable economically and environmentally.
